Using Jan Tielens SmartPart - Using the AJAX Control Toolkit in SharePoint in could be very interesting but sometimes you might get this horror error like
Sys.WebForms.PageRequestManagerParserErrorExeption: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near '_TextBox'.
You could get a very detailed article here from Mike Ammerlans Blog on how to integrate Ajax and WSS but it might not solve all the the issues and errors.
Another very good blog here is by Eric Lipton which tells you what is it and how to avoid it and you could get some good tricks when using Ajax in sharepoint or your normal ASP.NET apps.
After trying different scenario by placing the asp:ScriptManager beneath the WebPartManager registration (search for <WebPartPages:SPWebPartManager id="m" runat="Server" />):<asp:ScriptManager runat="server" ID="ScriptManager1"></asp:ScriptManager>
I also tried adding validateRequest=false and it didn't work
Even if you try to add them directly to your sharepoint pages WSS it will throw an error saying it doesn't want it.
I evntually added:
<pages enableEventValidation="false"/>
to my web.config and that did the trick.
Maybe there is an updated version of the AJAX Control Toolkit .But if you have the version
Version=1.0.10123.0 then bad luck you will need to do all these to get it going.
Hope that helps
